In the drawing, wherein -fornthepurpose of il lustration vis `shown* a preferred embodiment 'of' my invention, vthe numeral lI!! designates a metallicroofingelement or shingle, formedfof sheet metal or the like, whichmaybe suitably-resilient.-V This metallic shingle is provided atv. one longitudinal edge with a hollow rib or'bfead I I, which is preferably'oirculaily curvedin kcross'-sectioim and open'at its ends and one side, ai'ordiiig a longitudinal passager I2. .This rib'II fiesub'stantially semiecylindrical and extends" alici/@fthe shingle I Q and has itsopen side arranged inner# most withA respect to the shiiigle', so that the pas#-` sag'e l2 isedjeeeirtfto the shingle. The hjoiiow rib or bead Ijl is formed hy bending the material of thefsheet II) upon itself in an inward direction; forming an vinn'er."layerj Aor sheet I3, Aand then ,leeimi-i'ng the sheetepen the edge '14, baekup'e'n 5 itselffin an outward direction ailordinganouter sheetor layer I5, preferably snugly engaging the inner lay'er or sheet I I. The 'outer layer rsheet l5. is continuedfto ap'oint substantially'opposite ,l the p'afSSae I2, arid iS then bent horizontally to 10 'aiordan attaching extension or an'ge` I6, 'flush with the Sheet I0 or bdyportion ofthe shingle, This attaching extension has its1 rear end terriiihating with' the rear end of the shingle 'and forme fin'ga straight angle therewith, kwhile its forward end is fore'shorteiied and Aspaced from the forward end'of the shingle and ,parallel therewith. This attaching extensiori'orilango I6 `is provided with an upwardly loulgingrib` Il, coacting with the hollow rio 'or bead Il, to lafford adrainirig trough, for any water which may possibly pass over the hollowf bead orrih, lI. 'Il'hev attaching extension or flange I5 is preferably equipped with openings IS, for receiving riailsro'r the like.

'The' upper 'or4 rear e'n'd of. each hollow bead or rib II is cu't through loothlayersIS and'l5 to provider an Ainclined or ,diagonal edge |9, which extends from the edge I4 to the freefen'd of the rib and the attaching extension I6. The `forward or lower end of thezhollow rib or bead vII is so modiiied that it is readilyA insertable intothe-upf per or r'earendof the hollow rib or bead II of a companion shingle. Atits forward or lower end, the hollow 'ribor bead II vhas its outer layer I5 cut awayarid removed, the cutting alfordin'g an 35 inclined l or -diagonal edge 20, .whichy extends from theiongitudinal edge lIll tojfa pointil, which is 'spaced igetijcally 'from the attaching eten'sion or harige, I6, aordinga substantially Vertical shoull der V22,'leadirigto the edge 23.0ff the attaching 40 eXtensi'oh or flrfgf I6 Which is Space'd rearwardly asubstaritialdi'stanc from' the lower or forward end of the shingle IU, as shown. The upper layer l5 is also [out fromV the' lower layer' I3 .lengthe l edge mfrem vvthe end of thejdiegenai edge zarte 45 the free fend of th innerlayer It. n. The inner layer I3 wliihjlrojlfc'lsk outwardly and forwardly' beyond the upper layer I5 is tapered, forming an extension I3", decreasing diameter forwardly or downwardly Asothat it inaylbe readily inserted Within th' 'appl' 'Bhd' f 'the Cor'rip'al'loh h0110W rib or head. The edge portion I4 of `the inner layer kI3 remainsv parallel'with the shingle IU, asshown. t

" The opposite edge of the shingle l!! is bezit t provide a hollow rib or bead 24, projecting above the shingle, and having its lower edge 25 substantially flush with the lower surface of the shingle, and spaced therefrom, for affording a passage 25. The lower or forward end of the bead 24 is cut away from a point 2l, to the free edge of the bead or rib, affording a diagonal edge In assembling the shingles the lowermost shingle I in one upstanding row is first placed upon the roof adjacent to the lower edge of the roof so that the shingle shall suitably project below this lower edge and may be properly attached to the lower edge of the roof. 'Ihe next shingle I0 in the same row is now placed above the first shingle, with the tapered inner layer extension I3 arranged lowermost. This nextcompanion shingle to be placed in position may be slightly transversely inclined and the upper end of the bead 24 of the lowermost shingle will be guided into the lower end of the bead 24 of the companion upper shingle, by virtue of the diagonal edge 2B. AAfter the insertion has been started the next upper shingle is swung down to a flat position upon the upper end of the lowermost shingle, andthe taperedextension I3l will vnow enter the upper end of the rib II. The uppermost shinglelis now moved downwardly, and its attaching extension or flange I6 is brought over the upper end of the attaching'extension or flange I6 of the companion shingle whereby these ends overlap, the diagonal edge I9 extending behind the edge of shoulder 22, as clearly shown in Figure 4. The downward movement is continued 4 until the edge 20 engages the edge I9. y, It is thus seen that the adjacent ends of the extensions or flanges I6 overlap, the shoulder 22 overlaps a portion of the edge I9, and the tapered extension I3 unde'rlaps the meeting edges I9 'and 20. yAn exceedingly tight joint is therefore afforded. In laying the next row of shingles the hollow rib or bead 24 is passed over the assembled ribs or beads II and the shingle is moved downwardly to break joint with the overlapped ends of the assembled shingles in the completed row. The next shingle in the second row is applied in a similar manner so that its lower end will overlap the, upper end of the companion shingle in the same row. The extensions or flanges I6 in each row are nailed to the roof. The row of shingles next to the end of the roof is cut off and bent over the edge of the roof and nailed thereto. It is thus seen that the shingles are securely attached to the roof without the use of separate clips. The rib Il coacts with the rib I I for providing a trough to conduct away any water which may possibly pass the .assembled parts I I. The particular advantage in my construction is that the attaching extensions or flanges are permanently secured to the shingles and will therefore, be readily nailed to the roof. Where detachable c lips are used, workmen frequently fail to use a sufficient number of these clips, whereby the shingles are not securely attached to the roof. The use of attaching. extensions or flanges I6 involves a lconsiderable problem in the assembling of the shingles in the same row. In the patent to E. E. Barker, 381,318, an attempt has Vbeen made to solve the problem. This construction is not wholly satisfactory as the joint produced is not sufficiently tight. In this patent the meeting ends of the attaching flanges cannot overlap, but simply abut, and further, the outer layer is entirely cut away and the inner layer is partly cut away. In my construction the inner layer is not cut away but is rendered tapered, and

the outer layer is cut on a diagonal to the point 2|, affording a shoulder 22. In my construction the edge I9 extends behind this shoulder and the extensions I 6 overlap, and further the meeting edges I9 and 20 are spanned by the complete inner layer I3. A much tighter joint is effected.

It is to be understood that the form of my invention herewith shown and described, are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claims.
